eavesdrop on Mobile phones - 08/26/04 07:48 AM

How's it going everyone. This is my first post, so I hope its a good one. I remember the days when you could listen to someone speaking on their mobile phones using a scanner, back before everything went digital. I thought What if it is possible to eavesdrop on digital mobile phones. Well In my search for the answer, I came across an article saying that in china a new device had come on the market called a detectaphone. Basically you put someones mobile number in there, when they recieve or make a call, it gets recorded in this device so you can listen to it. The article said that the reporter tested it and it worked for him, but because of panic they went underground selling this thing, they said there were a few websites selling the thing, but I've done an exhaustive search and found nothing, just wondering if anyone knew anything more about them, or where to purchase one from. Or if there is another way of listening to other peoples phone calls made from a landline or mobile.

800MHZ digital phones/cellular phones could be listened to on 800mhz scanners (I have one, when we lived in our apartment it was interesting, learned more spanish as if i needed to).

It is not (as far as I know) possible (or if it is, easy) to eavesdrop on a digital phone as they use much stronger frequencies and some use differant security measures in order to not allow it (such as changing the frequency every 5 seconds).

I think what they claimed to have is a crock of [censored]; you can however monitor a landline phone by placing a micro recorder in the TNI box when it's hooked up to the line (note that it'll only record up to the length of what the tape permits). Also note that the type of microcasette recorder you will want is voice activated so that it'll only record when an active connection on the line is presant.
